Currently, the various drm bridge drivers relay on OF infrastructures to works very well. Yet there are platforms and/or don not has OF support. Such as virtual display drivers, USB display apapters and ACPI based systems etc. Add fwnode based helpers to fill the niche, this may allows part of the drm display bridge drivers to work across systems. As the fwnode based API has wider coverage than DT, it can be used on all systems in theory. Assumed that the system has valid fwnode graphs established before drm bridge driver is probed, the fwnode graphs are compatible with the OF graph. Tested on TI BeaglePlay board and other platforms. v1 at https://patchwork.freedesktop.org/series/129040/ v2: * Modify it66121 to switch togather * Drop the 'side-by-side' implement * Add drm_bridge_find_next_bridge_by_fwnode() helper * Add drm_bridge_set_node() helper Sui Jingfeng (4): drm/bridge: Add fwnode based helpers to get the next bridge drm/bridge: simple-bridge: Use fwnode API to acquire device properties drm-bridge: display-connector: Use fwnode API to acquire device properties drm-bridge: it66121: Use fwnode API to acquire device properties drivers/gpu/drm/bridge/display-connector.c | 24 ++++---- drivers/gpu/drm/bridge/ite-it66121.c | 63 +++++++++++--------- drivers/gpu/drm/bridge/simple-bridge.c | 22 ++++--- drivers/gpu/drm/drm_bridge.c | 68 ++++++++++++++++++++++ include/drm/drm_bridge.h | 16 +++++ 5 files changed, 142 insertions(+), 51 deletions(-) -- 2.34.1
